The function of automobile air-conditioning condenser is to heat and cool the high-temperature and high-pressure refrigerant vapor discharged from the compressor, and condense it into liquid high-pressure refrigerant.
It can cool and liquefy the high-pressure and high-temperature refrigerant (gaseous refrigerant) sent from the compressor. The following is an introduction to the working principle of automobile air conditioning condenser:
1. When the refrigerant enters the evaporator, the pressure decreases, and it changes from high-pressure gas to low-pressure gas. This process needs to absorb heat, so the surface temperature of the evaporator is very low, and then the cold air can be blown out by the fan The cold condenser is used to cool the high-pressure and high-temperature refrigerant from the compressor to high-pressure and low-temperature. Then it is vaporized by capillary tube and evaporated in evaporator.
2. Condensers and evaporators in automobile air conditioning are collectively referred to as heat exchangers. The performance of heat exchanger directly affects the refrigeration performance of automobile air conditioner. Its metal material consumption is large, its volume is large, and its mass accounts for 50% ~ 70% of the total mass of the whole automobile air conditioning device. The space it occupies directly affects the effective volume of the automobile, and it is difficult to arrange. Therefore, it is extremely important to use high-efficiency heat exchanger. The condensers and evaporators in the automobile air-conditioning equipment should match with the compressors and the throttling expansion mechanism. The working state of the condenser and evaporator directly affects the capacity of the refrigeration system (refrigerating capacity), the power consumption of the compressor and the economy of the whole air conditioning unit.
